Thank you for the clear explanation.
Now when I reboot/restart the miner, which .sh will be run?
The old (cgminer.sh) or the new zzz.sh?
Thanks!

What do you mean restart the miner?
sed sBD1BF1B /config/zzz.sh ; /config/zzz.sh restart
Does it rewrites the zzz.sh file? or its only in memory and resets when miner is rebooted?
Thanks!
sed sBD1BF1B /config/zzz.sh ; /config/zzz.sh restart
Does it rewrites the zzz.sh file? or its only in memory and resets when miner is rebooted?
Thanks!
You probably shouldnt be monkeying around with your miner if you don't understand the SED command... You've been warned.
The substitute command changes all occurrences of the regular expression into a new value. In the case above, it is substituting BD1BF1B in the cgminer.sh file and creating a new zzz.sh file. The command then runs the zzz.sh script

Hi ,
Great information. Thank you all!
Now if after using this:
sed sBD1BF1B /config/zzz.sh ; /config/zzz.sh restart
I would like to go back to the original (previous) setup, What do I have to type?
sed
How do I back up the original file?
Thanks!

Just restart the miner.
First of all there is a little cheating. I have six boards.
I've set to 432, I gave a little more voltage. On the picture you can see there is a die with about 48 watt. Maybe this is a weaker die beacuse it turned off-on, so I gave it a little more voltage, it remained turned on, but the vrm went to fault. I had to played with the voltages a bit but now it's fine.
But I saw only 850 at pool. (If anybody have ideas what cause this help would be appriciated). So I've started to play with the SPI, so now the HW is getting worse and worse (I forgot to write down the SPI with I had low HW). So i'm not so happy now....
lol! It's not the first time I fall briefly for your 6 boards but it usually last only a couple of seconds of bewilderment.
No ideas except: what about the old hotter is better trick? A lot riskier playing with this but... I do see you have boards at 39 C (boards not asic, remember, so it's risky). Though I guess all the "hot" trick did before was to slightly change the VRM parameters in the first place...
r1etc: yes, I am running a full 8 VRM jupiter, 597.4 avg (the upper left "(avg)") at cgminer with 1F1. Amps as previous post. Temps 38 to 54. Four of the VRMs per board remain off (as, I guess, one should expect...).
Mybe the hotter trick could be wrok but I put some high cfm fans into the box and closed it. I'm just too lazy to reopen and play with it. I hope I'll go up with clock and amp to get enough heat.
You stated earlier you were changing the SPI. I guess that's the general one stated as SPI in the upper left (even if they're all "SPI"). I find that changing the voltages seems to work better core by core even if you do small changes and even if it is the same change to all the cores.
Temp may have just been the old way of increasing the amps.
Impressive stuff Tolip
Looking forward to having the time (and a bit the courage) to do a customised board by board tweak anywhere close yours.
Currently sitting on SPI 512000Hz.
You can figure out the voltages die by die but I didn't had enough time for that. I've just give a bit more for all dies. (from cpu tuning, more clock needs some more voltage). I had one die wich turned on-off repeatly. For this one I had to give much more voltage but now it pulls 55amp and 48w.
All my asic runs with 432 except the weaker one, it's runs with 1f1. Now I got 965 at cgminer and between 980-990 at pool.
At the weekend I'll install Bfgminer and try to figure out core by core.
I've asked Wen, if he could give a table with clock settings would be great cause I move in the dark right now. For example I don't know 432 is what clock but it works good.

Could you post us the codes for the mhz-s in a list?

The following is my HW errors per core (hand did editing)
Clock and power list
A study of HW errors over time @ 900+
You can tell the ASIC is thermally limited.
THIS MACHINE IS WATER COOLED
(not just a one piece WB kit but serious water action)
Sometimes higher clock is lower HW error.
Enjoy!

How do you do this with bfgminer? When you launch bfgminer with the command "./bfgminer -S knc:auto -c /config/cgminer.conf" will that then use the modified cgminer.sh file or do I need to follow the instructions at https://bitcointalksearch.org/topic/m.3714194 to copy the cgminer.sh and make my own bfgminer.sh file?
Thanks for the help
Thanks for the help
You have to modify the COPY of the cgminer.sh to start bfgminer instead.
details at link below
https://bitcointalksearch.org/topic/m.3714194
You might could start a modified cgminer.sh, stop it and use
"./bfgminer -S knc:auto -c /config/cgminer.conf"
EDIT and I'm ignorant for pointing you to a link included in your post, lol

As I said I am using an 8 VRM miner... and have a question I was hoping someone could answer. When I SSH into my miner and apply the patch for 7% or so boost.. it seems like it's super fast for a little while but tends to slow down a bit after running for a while. At least that's what it looks like when I have my SSH window open. Can anyone tell me why and perhaps how to remedy?
- .m.w. -
- .m.w. -
from us early batch users, we saw that the 4 VRM build doesn't have any hardware protection for overvoltage/current while the 8VRM boards did. That is why when they switched from 8 to 4, the boards with 4 VRMs shot up since they didn't have to bother with firmware protecting it. Later they finally changed it to limit it.
I probably don't have the exact facts (since their spokesperson kept avoiding the issue as moot) but that is the jist of it.
Some say that the very first 8 VRM machines did run higher with .90 firmware but they had trouble getting it back that way once they switched. Even when going back to .90.
tl;dr so who knows.. the 8 VRM boards just have more protections on voltage/current
Hmm.. So I wonder if flashing the Beaglebone with the recovery image would make any difference? I guess it couldn't hurt to give it a try.
Edit
I see the the firmware is actually 0.96 if you flash it. But there is an iso file in there called U-Boot.iso that I wonder if I can rebuild to use 0.90 instead of 0.96 so that it never sees the later image?
I guess no one has input into how harmful OCing a Jupiter would be?
I haven't even began to tinker with my Jupiter, I am quite content @ 590GH/s.
How high can I push this thing though? It doesn't seem to be extraordinarily hot.

First of all there is a little cheating. I have six boards.
I've set to 432, I gave a little more voltage. On the picture you can see there is a die with about 48 watt. Maybe this is a weaker die beacuse it turned off-on, so I gave it a little more voltage, it remained turned on, but the vrm went to fault. I had to played with the voltages a bit but now it's fine.
But I saw only 850 at pool. (If anybody have ideas what cause this help would be appriciated). So I've started to play with the SPI, so now the HW is getting worse and worse (I forgot to write down the SPI with I had low HW). So i'm not so happy now....
lol! It's not the first time I fall briefly for your 6 boards but it usually last only a couple of seconds of bewilderment.
No ideas except: what about the old hotter is better trick? A lot riskier playing with this but... I do see you have boards at 39 C (boards not asic, remember, so it's risky). Though I guess all the "hot" trick did before was to slightly change the VRM parameters in the first place...
r1etc: yes, I am running a full 8 VRM jupiter, 597.4 avg (the upper left "(avg)") at cgminer with 1F1. Amps as previous post. Temps 38 to 54. Four of the VRMs per board remain off (as, I guess, one should expect...).
Anyone able to get 8-VRM modules to work with this? I have a mix of 4-VRM and 8-VRM modules and the overclock settings only appear to affect the 4-VRM units.
El gabo!
Care to share the settings in more detail? 211? More voltage?
Just want to share that my 8 VRM miner is still alive though it's not quite getting to 600 with 1F1. The disabled VRMs don't come up with this. I think it would be an advantage to figure out how to turn all 8 and get a Novemberish design. Was there any reason apart from a VRM shortage why they couldn't turn on all 8? I saw someone say there was a problem with them working in pairs???
